Examines the long-term impact of historic beaver trapping in the United States on stream systems, the role of beaver trapping in arroyo formation in the American Southwest, why the significance of beavers was missed by the U.S. General Land Office surveys in the late 1700s to mid 1800s, and how that oversight impacted later researchers in the 1950s and 1960s as the study of fluvial geomorphology and hydraulic geometry emerged.

A comprehensive compilation of information related to beavers and their management with an emphasis on stream restoration.

This report shares the experiences and lessons learned regarding the use of beaver for restoration and climate change adaptation in a selection of American states: California, New Mexico, Oregon, Utah, Washington and Wyoming.

This landmark 20 year study compares traditional lethal beaver control versus nonlethal management methods in the town of Billerica, MA. A total of 55 beaver conflict sites were studied. Sites that were managed with nonlethal control methods cost taxpayers significantly less than sites that were managed with beaver removal, and provided millions of dollars of ecological services to the town annually that would have been lost with beaver removal.

This publication, guided by the inseparable nature of streams and riparian ecosystems, emphasizes the interrelationships and continuity of riparian areas along with dependent wildlife and human services.
